+- **Internal "continue where you left off" prompts no longer leak into the visible transcript when a response is truncated by the output-length cap or a too-large tool call.** When the agent's response is cut short it emits a `[System: …]` continuation prompt, which the WebUI hides from the chat. The filter only matched the network-error variant (it required the literal "cut off by a network error" phrase), so the output-length and tool-call-too-large variants rendered as stray system bubbles. The filter now matches any `[System: …]` prompt carrying either "continue exactly where you left off" or "do not retry the same tool call", covering all three variants while still leaving genuine non-`[System:]` messages alone. Thanks @rodboev. (#4880, closes #4875)
